Light-based treatments have revolutionised aesthetic medicine, offering effective solutions for everything from pigmentation and redness to hair removal and skin rejuvenation. However, the terms “laser” and “IPL” are often used interchangeably, leading to confusion about which technology is best suited to specific skin concerns. At Axiom Aesthetics, we believe informed patients make better treatment decisions, so let us clarify the key differences.
Understanding the Fundamentals
What Is Laser Treatment?
LASER stands for Light Amplification by Stimulated Emission of Radiation. A laser device emits a single, concentrated wavelength of light that targets specific chromophores (light-absorbing molecules) in the skin. Because the light is coherent and monochromatic, it can be precisely directed to specific depths and structures within the skin.
There are numerous types of aesthetic lasers, each designed for specific purposes:
- Alexandrite (755nm): Excellent for hair removal on lighter skin types
- Nd:YAG (1064nm): Safer for darker skin types; used for hair removal, vascular lesions, and skin rejuvenation
- Diode (810nm): Versatile hair removal laser effective across multiple skin types
- CO2 (10,600nm): Ablative laser for skin resurfacing, scar treatment, and wrinkle reduction
- Erbium:YAG (2940nm): Ablative laser with less thermal damage than CO2, suitable for more superficial treatments
- Pulsed dye laser (595nm): Targets haemoglobin for treatment of redness, rosacea, and vascular lesions
- Q-switched lasers: Deliver ultra-short pulses for pigmentation and tattoo removal
What Is IPL?
IPL stands for Intense Pulsed Light. Unlike lasers, IPL devices emit a broad spectrum of light wavelengths (typically 500-1200nm), filtered to target specific concerns. Think of it as a flash of white light with certain colours filtered out, compared to a laser’s single-colour beam.
IPL is sometimes called a “photofacial” or “broadband light” (BBL) treatment. Because it emits multiple wavelengths simultaneously, it can address several skin concerns in a single session, though with less precision than targeted laser therapy.
Key Differences Between Laser and IPL
Precision and Specificity
Lasers offer superior precision because they emit a single wavelength that can be accurately matched to the target chromophore. This means less energy is wasted on surrounding tissue, resulting in more efficient treatment with fewer sessions. IPL’s broad-spectrum approach means some energy is absorbed by non-target structures, which can reduce both efficacy and safety in certain situations.
Skin Type Suitability
This is one of the most critical differences. IPL carries a higher risk of complications (particularly burns and hyperpigmentation) on darker skin types (Fitzpatrick IV-VI) because the broad spectrum of light can be absorbed by melanin in the surrounding skin. Specific lasers, particularly Nd:YAG, can be safely used on darker skin types because their longer wavelength penetrates deeper with less melanin absorption at the surface.
The British Association of Dermatologists recommends that patients with darker skin types seek treatment with Nd:YAG lasers rather than IPL for this reason. At our clinic, we always perform a thorough skin assessment to determine the safest and most effective technology for your individual skin type.
Treatment Depth
Lasers can be engineered to penetrate to very specific depths within the skin. This allows practitioners to target structures at precise levels — from superficial pigment in the epidermis to deeper vascular structures and hair follicles. IPL energy is more scattered, making it better suited to superficial concerns across a broader area.
Downtime and Recovery
Generally, IPL treatments involve less downtime than laser procedures, particularly when comparing with ablative lasers like CO2 or Erbium. However, non-ablative lasers can have similar downtime profiles to IPL. The specific downtime depends more on the treatment parameters (energy, pulse duration, spot size) than on whether the device is a laser or IPL.
Comparing Results by Condition
Hair Removal
Laser hair removal is generally considered the gold standard. Diode and alexandrite lasers offer the most efficient permanent hair reduction, typically requiring 6-8 sessions for optimal results. IPL can also achieve good hair reduction but typically requires more sessions (8-12) and is less effective on finer hair. Nd:YAG lasers are the safest option for darker skin tones.
A systematic review in Lasers in Medical Science (2022) found that diode lasers achieved a 70-80% hair reduction after six sessions, compared to 50-60% for IPL under similar protocols.
Pigmentation
For focal pigmented lesions such as sunspots and age spots, Q-switched lasers provide the most precise and effective treatment, often clearing lesions in 1-3 sessions. IPL is better suited to diffuse, superficial pigmentation across a larger area, such as generalised sun damage. For conditions like melasma, neither IPL nor most lasers are first-line treatments, as they can worsen the condition — careful assessment is essential.
Redness and Vascular Concerns
Pulsed dye lasers (PDL) are the gold standard for treating vascular conditions including rosacea, thread veins, and port wine stains. IPL can also effectively treat mild to moderate redness and diffuse flushing, particularly the BBL platforms. For larger or deeper blood vessels, Nd:YAG lasers provide better penetration.
Skin Rejuvenation
Both technologies can achieve effective skin rejuvenation. IPL/BBL is excellent for overall skin tone improvement, treating the combination of mild pigmentation, redness, and texture irregularities in a single session. Ablative and non-ablative fractional lasers provide more dramatic results for wrinkles, acne scars, and skin texture, but with greater downtime.
Acne and Acne Scarring
For active acne, certain IPL wavelengths can reduce acne-causing bacteria and inflammation. However, for acne scarring, fractional lasers (both ablative and non-ablative) are significantly more effective, as they can remodel collagen at deeper levels within scar tissue.
Safety Considerations
Both laser and IPL treatments are safe when performed by qualified practitioners using appropriate parameters. However, there are important safety considerations:
- Practitioner expertise: The skill and experience of the practitioner is often more important than the specific device used. At Axiom Aesthetics, all our light-based treatments are performed by trained and insured professionals
- Skin assessment: A proper skin type assessment is essential before any light-based treatment. This includes evaluating Fitzpatrick skin type, recent sun exposure, medication use, and any active skin conditions
- Test patches: We recommend test patches for new patients, particularly with IPL treatments, to assess skin response before treating larger areas
- Sun avoidance: Both during and after treatment courses, sun protection is critical. Tanned skin increases the risk of adverse effects with both technologies
- Contraindications: Pregnancy, certain medications (including some antibiotics and retinoids), active infections, and recent tan are contraindications for both laser and IPL treatments
Cost Comparison
IPL treatments are generally less expensive per session than laser treatments, reflecting the lower equipment costs and broader treatment approach. However, because IPL often requires more sessions to achieve comparable results, the total treatment cost may be similar. Laser treatments typically offer greater efficacy per session, potentially making them more cost-effective overall.
We provide transparent pricing during your consultation and can help you understand the likely total investment for your specific treatment goals.
Making Your Decision
The best technology for you depends on several factors:
- Your specific concern: Some conditions respond better to laser, others to IPL
- Your skin type: Darker skin types are generally safer with specific laser wavelengths
- Your budget and timeline: Laser may require fewer sessions but at a higher per-session cost
- Your downtime tolerance: Some laser treatments require more recovery time
- Your goals: Generalised improvement vs. targeted correction of specific lesions
We always recommend a professional consultation to determine the most appropriate technology for your needs. Contact us to arrange your assessment.
Frequently Asked Questions
Is laser treatment more painful than IPL?
Pain perception varies between individuals and depends heavily on the treatment area and device parameters. Generally, IPL is described as a warm snapping sensation, while laser can feel like a sharper pinprick. However, modern cooling technologies integrated into both laser and IPL devices have significantly improved comfort. Topical anaesthetic can be applied for more sensitive treatments or areas.
Can I have IPL or laser treatment if I have a tan?
No. Both IPL and laser treatments carry increased risks when performed on tanned skin, including burns and hyperpigmentation. We recommend avoiding sun exposure and self-tanning products for at least 4-6 weeks before treatment. This is particularly important for IPL, which has a broader absorption profile. Your practitioner will assess your skin at each session and may postpone treatment if you have been recently sun-exposed.
How many sessions will I need?
The number of sessions depends on the condition being treated, the technology used, and your individual response. As a general guide: hair removal requires 6-8 laser sessions or 8-12 IPL sessions; pigmentation may clear in 1-3 laser sessions or 3-5 IPL sessions; skin rejuvenation typically involves 3-6 sessions of either technology. Your practitioner will provide a personalised treatment plan during your consultation.
Are the results permanent?
This depends on the condition. Laser hair removal can achieve permanent hair reduction (not complete removal) after a full course. Pigmentation treatment results can be long-lasting but new sun damage can create new spots. Vascular treatments may need occasional maintenance as new blood vessels can develop. Skin rejuvenation results are progressive and can be maintained with annual top-up sessions and good skincare.
Can laser or IPL treatments be combined with other aesthetic procedures?
Yes, both can be part of a comprehensive treatment plan. However, appropriate spacing between different treatments is important. For example, we typically recommend waiting 2-4 weeks between light-based treatments and injectable treatments. Chemical peels and light-based treatments should also be appropriately spaced. Your Axiom Aesthetics practitioner will create a treatment timeline that safely combines multiple modalities for optimal results.
